Abstract

EL GENERADOR (10) DE GAS SE COMPONE DE UNA CARCASA (12), EN LA QUE ESTA FORMADA UN ESPACIO (24) DE RESERVA PARA EL GAS (28) LIQUIDO. EL ESPACIO (24) DE RESERVA ESTA SEPARADO A TRAVES DE UNA PARED (26) DE SEPARACION DE UN ESPACIO (40) DE COMBUSTION PREVIA FORMADA ASIMISMO EN LA CARCASA (12). EN UN ESPACIO (34) DE PRECOMBUSTION ESTA UNIDO UN DISPOSITIVO (32) DE ENCENDIDO, CUYA CARGA DE ENCENDIDO GENERA LA INFLAMACION DEL GAS DE COMBUSTION. EN EL ESPACIO DE PRECOMBUSTION (34) SE GUIA DE FORMA DESPLAZABLE UN EMBOLO (36), QUE SE NUEVE DEBIDO AL GAS DE COMBUSTION DE LA CARGA DE ENCENDIDO EN EL ESPACIO (40) DE COMBUSTION HACIA ADENTRO Y POR MEDIO DE EL HACIA LA DIRECCION SOBRE LA PARED (26) DE SEPARACION, PARA SU INTERRELACION. EN LA PARED (26) DE SEPARACION DE INTERRELACION SE ENCUENTRA UNA UNION A TRAVES DEL SISTEMA (58, 60) DE CANALES DEL GAS LIQUIDO ENTRE EL ESPACIO (24) DE RESERVA Y EL ESPACIO DE COMBUSTION, DE FORMA QUE EL GAS (28) LIQUIDO PUEDE SER INTRODUCIDO EN EL ESPACIO (40) DE COMBUSTION. AL MISMO TIEMPO SE CONSIGUE UNA UNION A TRAVES DEL CANAL (66) DE ENCENDIDO FORMADO EN EL EMBOLO (36) ENTRE EL ESPACIO (34) DE COMBUSTION PREVIA Y EL ESPACIO (40) DE COMBUSTION PRINCIPAL. LOS GASES DE COMBUSTION DE LA CARGA DE ENCENDIDO INFLAMAN EL GAS LIQUIDO A INTRODUCIR EN CIRCULACION. LA PRESION INTERNA CRECIENTE EN EL ESPACIO (40) DE COMBUSTION PRODUCE LA TRASLACION DE LA PARED DE SEPARACION GUIADA EN UN DESPLAZAMIENTO DE DIRECCION LONGITUDINAL, QUE SE MUEVE CONJUNTAMENTE CON EL EMBOLO (36) Y CON ELLO EL GAS (28) LIQUIDO CONTINUAMENTE SE INYECTA DESDE EL ESPACIO (24) DE RESERVA EN EL ESPACIO (40) DE COMBUSTION. LOS GASES DE COMBUSTION (40) APARECEN DE FORMA LIBRE A TRAVES DE ESPACIOS (48,54) ANULARES CONECTADOS EN SERIE POR MEDIO DE ABERTURAS (56) DE SALIDA.THE GAS GENERATOR (10) IS COMPOSED OF A CASE (12), IN WHICH A SPACE (24) FOR THE GAS (28) LIQUID IS FORMED. THE RESERVE SPACE (24) IS SEPARATED THROUGH A SEPARATION WALL (26) FROM A PREVIOUS COMBUSTION SPACE (40) ALSO FORMED IN THE HOUSING (12). IN A PRE-COMBUSTION SPACE (34) IS UNITED AN IGNITION DEVICE (32), WHOSE CHARGE OF IGNITION GENERATES COMBUSTION GAS INFLAMMATION. IN THE PRECOMBUSTION SPACE (34) A PISTON (36), WHICH IS NINE DUE TO THE COMBUSTION GAS OF THE IGNITION CHARGE INTO AND THROUGH THE DIRECTION OF COMBUSTION, IS NUMELY GUIDED ON THE WALL (26) OF SEPARATION, FOR YOUR INTERRELATION. IN THE INTERRELATION SEPARATION WALL (26) IS A JOINT THROUGH THE SYSTEM (58, 60) OF LIQUID GAS CHANNELS BETWEEN THE RESERVE SPACE (24) AND THE COMBUSTION SPACE, SO THAT THE GAS (28) LIQUID MAY BE INTRODUCED IN THE COMBUSTION SPACE (40). AT THE SAME TIME A JOINT IS ACHIEVED THROUGH THE IGNITION CHANNEL (66) FORMED IN THE PLUG (36) BETWEEN THE PREVIOUS COMBUSTION SPACE (34) AND THE MAIN COMBUSTION SPACE (40). THE COMBUSTION GASES OF THE IGNITION CHARGE INFLATE THE LIQUID GAS TO BE INTRODUCED IN CIRCULATION. THE INCREASING INTERNAL PRESSURE IN THE COMBUSTION SPACE (40) PRODUCES THE MOVEMENT OF THE GUIDED SEPARATION WALL IN A DISPLACEMENT OF LONGITUDINAL DIRECTION, WHICH MOVES TOGETHER WITH THE BOTTLE (36) AND WITH IT THE GAS (28) CONTINUOUSLY INJUTES LIQUID FROM THE RESERVE SPACE (24) IN THE COMBUSTION SPACE (40). COMBUSTION GASES (40) APPEAR FREE OF CHARGE THROUGH ANNULAR SPACES (48.54) CONNECTED IN SERIES THROUGH OUTLET OPENINGS (56).
